DESK ATTACHMENT.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application led February 15, 1909. Serial No. 477,923.

` `To all whom tt may concern:

Be it known that I, MARGARET TENNENT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Desk Attachments, of which the following is a specification.

Myinvention relates to desk attachments, particularly intendedy to hold a series of uidreceptacles. It is illustrated in the 'accompanying drawings, wherein- I1`1gure` l is a side elevation with arts broken away and other parts in dotted lmes; `Fi .y 2 is a similar view with the parts in d1 erent positions; Fig. 3 is a horizontal section, and Fig. 4 is a rear elevation. Fig.

` 5is a detailtop view. Fig. 6 is a longitudinal vertical section through Fig. 3 looking toward the front.`

Like parts are indicated by the same letter in all the figures. j

A is the back, B the top, and C the bracket ofthe school desk.

D is a case'which contains the movable parts of my attachment. It is somewhat in the shape of a rectangular box. The back fof this case is preferablyyprovided with a series of perforations as E and is preferably associated with a plate F havin()f a series of j. similar registering perforationsl-E.

G, G are bolts which pass through the C back plateL and the securing plate and of these partitions also has at its forward end inwardly projecting flanges D4 D1 and the sides of the boX have similar flanges. In each j' ,of ythese compartments there is a sliding re- 59fceptacle J. The front J1 ofeach of these receptacles is preferably provided with a lower extension J 2` which underlies the bottom of said receptacle and terminates in a thumb piece J 3 whereby the sliding receptaclemay be manipulated. Each of these receptacle fronts J1 is provided above with an inwardly overhanging lip or flange J 1 to assist in making a tlght joint between the receptacle and the case when the receptacle is pushed into its compartment. Each of these sliding receptacles is provided with a back K which has outwardly extending vertical flanges K1 to underlie the vertical flanges D4 on the front `of the partitions. The flanges K1 are cut away below atKz so as to permit the receptacle to slide in alono the ledge D3 and between the walls D2 D2. L is a liquid receptacle which I have shown in Fig. l. Of course, the sliding receptacles themselves could be the receptacles for holding liquids or solids, and in most cases it will not be desirable to use an inner receptacle.

The ledge Da and the lower side projections D2 are simply shown as one means for guiding the receptacle at its lower part of contracting the walls of its compartment below, so as to make it run and fit smoothly in the interior of the com artment. Other constructions, of course, might be employed for this purpose.

It will be understood that I do not wish to be limited to the precise form and construction shown and that in ay sense my drawings are to be taken as diagrammatic.

Some of the parts could be omitted and others varied without departing from the spirit of my invention, but I shall set forth in my claims what I consider' to be essential.

The use and operation of my invention are as follows: The structure shown illustrates one method of attaching my device. It conssts in having a largo number of perforations in the back of the case with bolts so as to afford an accommodation for the irregularly distributed apertures in the ordinary bracket.` The securing plate which I have shown is perforated so as to receive the heads of the bolts. It could be dispensed with where the apertures in the bracket are small or where the heads of the bolts are large. The preferred form for the purpose of attaching to the ordinary school desk bracket is that shown, wherein the back plate is provided with many perforations and a securing plate similarly perforated is used. lVhen the parts are in position, as indicated .in lfull lines in Fig. 1, the Hange at the top of the front of the sliding receptacle engages and underlies the top of the case so as to make a tight joint and cover the interval which would otherwise be left between ,theV top of the case and the front of the re- `thumb piece J3 is grasped and the sliding receptacle is pulled out where access can be had to its contents 4or to the contents of the inner receptacle which it may contain. Wvhen the sliding receptacle is to be removed, it is only necessary to lift it up from the position shown in Fig. 1 to that of Fig. 2, the flanges K1 sliding` up between the flanges Dc and theV front edge4 of the top of the case. When the receptacle is pushed in it is guided below because its side walls are in engagement with the side projections D2 of the ledges D3. It is kept from being pulled entirely out on a horizontal plane, by the engagement of the flanges K1 with the flanges D4.

I have shown my attachment as applied underneath the projecting side edge of a desk top, but of course it could be attached in any other desired position, and, as previously stated, could be fastened by screws to wooden or iron supports instead of bolts and the securing plate. Y

I claim:

l. A desk attachment comprising a case having a series of compartments eachof less width below than above, partitions between each compartment having vertical flanges at their sides and proj-ectingbeyond the front edge of the top of the case and a perforated back, with a perforated securing plate, se-

curing bolts passing each through registering perforations in the back and the securing plate, and a series of receptacles each provided with an upper flange underlying and engaging the front edge ofthe case when the receptacles are in closed position, said vertical flanges on the receptacles being substantially as long as the height of the wider portion of the compartment.
